 Jessica Alba, browsing for vintage couture with hubby Cash Warren at Annie Creamcheese in Georgetown. And the actress – in a beige sweater and high-waisted sailor pants – didn't come empty-handed: Alba brought along a video camera and interviewed sales staff about Washington, D.C., and the inauguration during her 30-minute shopping trip. Alba also left with a treat for herself: a black Ferragamo blazer for $395. "She was in such a good mood," says a source.

Cash Warren can thank his wife Jessica Alba for giving him a surprising and emotional birthday.

Warren celebrated his 30th with 80 of his family and friends at Tao Las Vegas in a celebration Saturday night put together with secrecy and military precision by Alba.

Telling her husband they were having a quick getaway to Vegas, the couple headed to Sin City on Saturday morning. After they checked into the penthouse at Palazzo Las Vegas, Alba, 27, took Warren to the Canyon Ranch Spa.

"She knew his entire party was checking in so she wanted him to be away from everything so no one would spoil the surprise," a source at the party tells PEOPLE.

For their first trip with 3-month old baby Honor Marie, Jessica Alba and husband Cash Warren feared the worst. But they got what every couple with a newborn hopes for: A quiet flight.

"It's always nerve-racking for new parents to fly with their child because you never know if you're going to ruin everyone else's flight with a screaming baby," Warren wrote on his blog ibeatyou.com about their first trip as a family – a jaunt from Los Angeles to Denver for last week's Democratic National Convention.

"We sit down and cross our fingers that she will sleep," continued Warren, 31. "She does .... Nothing really exciting happened on the flight except the energy of what was to come was already palpable."

NBA star Baron Davis, who has known Cash Warren since childhood, says he was ecstatic to meet his friend's newborn daughter with wife Jessica Alba.

"Oh, I couldn't wait to see them after the baby was born," Davis, who is also Warren's business partner in Verso entertainment, tells PEOPLE exclusively. "They are the picture-perfect happy family."

As for who baby Honor Marie takes after, he jokes: "Honor has their looks and my personality. All she did was yell." Then he adds, "No, seriously, she is a beautiful baby girl. She totally takes after Jessica."

According to a source, they were married in the Beverly Hills courthouse's ceremony room under an arch of green silk foliage and white flowers. They were casually dressed, with Alba wearing a long blue dress and her hair back in a ponytail.

"She looked happy but nervous," the source says.

Warren, in a white shirt and brown pants, arrived with Alba at about 11:30 a.m. on Monday, applied for a marriage license and waited about 40 minutes for the paperwork to be processed before a staff member from the courthouse married them, the source says.

Jessica Alba and fiancé Cash Warren are making the final preparations for their first child – and the actress says time's running out.

"I'm just trying to get my house ready before the baby comes," Alba, 26, said Wednesday night at PEOPLE's book party for Healthy Child Healthy World author Christopher Gavigan. "It's kind of hectic, it's getting close and the house isn't even ready yet."

With Alba taking time off from acting, she's handling the bulk of the duties to get ready for baby, which Alba revealed recently is a girl.
